[Zabbix] Tomcat 监控
一、安装 Tomcat
# cd /usr/local/src/tarbag/
# tar -zxvf jdk-8u144-linux-x64.tar.gz
# tar -zxvf apache-tomcat-9.0.0.M22.tar.gz
# mv jdk1.8.0_144 /usr/local/java
# mv apache-tomcat-9.0.0.M22 /usr/local/tomcat9
# vi /etc/profile
|
export JAVA_HOME=/usr/local/java CLASSPATH=/usr/local/java/lib/dt.jar:/usr/local/java/lib/tools.jar PATH=/usr/local/java/bin:$PATH export PATH JAVA_HOME CLASSPATH |
# source /etc/profile
# java -version
|
java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode) |
#/usr/local/tomcat9/bin/startup.sh #启动tomcat
# url登入http://192.168.1.208:8080看看欢迎界面
二、zabbix server端配置
Java支持
编译安装zabbixserver需要加上--enable-java以支持jmx监控，如果之前的zabbix server没加，那么请重新编译安装, 分享下我的安装参数：
|
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2 --enable-java |
----------------------------------------------------------------------------------------------------------
# yum -y install zabbix-java-gateway #我是yum安装
# vi /etc/zabbix/zabbix_proxy.conf
|
Server=10.254.0.3 ServerPort=10051 Hostname=Zabbix_proxy01 LogFile=/var/log/zabbix/zabbix_proxy.log LogFileSize=0 PidFile=/var/run/zabbix/zabbix_proxy.pid DBHost=10.254.0.4 DBName=zabbix_proxy DBUser=zabbix DBPassword=zabbix JavaGateway=192.168.1.208 JavaGatewayPort=10052 StartJavaPollers=5 SNMPTrapperFile=/var/log/snmptrap/snmptrap.log CacheSize=4G Timeout=4 ExternalScripts=/usr/lib/zabbix/externalscripts FpingLocation=/usr/sbin/fping LogSlowQueries=3000 |
# vi /etc/zabbix/zabbix_java_gateway.conf
|
默认就好 |
# systemctl restart zabbix-proxy
# systemctl restart zabbix-java-gateway.service
三、配置Tomcat JMX
# vi /usr/local/tomcat9/bin/catalina.sh
|
# ----- Execute The Requested Command ----------------------------------------- #一定要添加到这一行下面，不然失效 CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"
# Bugzilla 37848: only output this if we have a TTY |
# cd /usr/local/tomcat9/bin/
# ./shutdown.sh
# ./startup.sh
# lsof -i:10052
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

# java -jar/root/cmdline-jmxclient-0.10.3.jar - 192.168.1.208:12345 | sort #查看能监控的项
# java -jar/root/cmdline-jmxclient-0.10.3.jar - 192.168.1.208:12345 Catalina:port=8080,type=Connector #查看能监控的项
# java -jar/root/cmdline-jmxclient-0.10.3.jar - 192.168.1.208:12345 Catalina:port=8080,type=ConnectorprocessorCache #取值
# cmdline-jmxclient-0.10.3.jar 下载地址：点击打开链接
四、WEB端设置
# 利用zabbix3 自带的两个JMX 模板
